[This review was collected as part of a promotion.] The Energizer Ultimate Lithium 9V Battery is great with a 10 year shelf life. Well built square body frame that is leak proof.It has a manufacture date on it so you know when it is made and how long it last.
[This review was collected as part of a promotion.] I popped this Energizer lithium 9 volt battery in my smoke detector a while back and I’m sleeping peacefully knowing that it will work for a long time. I always use Energizer batteries and have not been disappointed.
[This review was collected as part of a promotion.] Do you keep your batteries in the refrigerator to try to make them last longer? Are you often frustrated that even when getting "new" batteries out of said fridge they just don't seem to be all that fresh and new and the correct voltage?
If so, I suggest you look into getting the Energizer Ultimate Lithium line of batteries.
The 9v are supposed to last 10 year on the shelf, or in my case (and I have started a non scientific research project on this) 10 years as a backup battery source in my AC powered smoke alarms.
They were put in new and had more than 9 volts power on my digital multimeter (approximately 9.3 volts) and in 1 year I will check the voltage on them again.
I plan to do continue to check them at least once a year until the voltage drops below the minimum voltage recommended by my smoke alarm manufacture.
If I can get 5 years out of these batteries I will be about breaking even on my battery costs, as I was replacing my old 9 volt batteries every 18 to 24 months. So this battery costing a bit more is offset by only buying 1 battery versus 2 to 3 batteries every 4 to 4.5 years. If I get 6 years on this battery, then it is saving me money.
[This review was collected as part of a promotion.] I needed a replacement battery for my smoke alarm, so I got the Energizer Ultimate Lithium 9v battery. I trust the brand of Energizer so I know this will be a long lasting and great battery. I won't have to replace this for a very long time.
[This review was collected as part of a promotion.] I needed this battery to change out an old one in my fire alarm. Energizer is well known for their long lasting batteries so I know this will last me for a long time coming. They are usually on the pricey side but if you want a good quality battery I would highly recommend going with Energizer.
[This review was collected as part of a promotion.] I get these batteries for my smoke detectors. Since we change the batteries Daylight Savings weekends, I want to feel confident they will last until the next change. Energizer batteries have been part of our “staple” items for years due to that peace of mind!
[This review was collected as part of a promotion.] What can you say. It's an Energizer battery. The name continues to speak for itself. Great battery with a stellar reputation for being reliable. These lithium batteries are awesome. Great power and great life. I use the AA's in my home security cameras and they last a long time. I have this 9v in a smoke detector. I know I'll should replace it after a year but it will probably last 3.
[This review was collected as part of a promotion.] The Energizer Ultimate Lithium 9 volt battery is wonderful because they last 4x longer than alkaline. Also they are great for high temperatures and 100% leak proof. I used this for my smoke detector and I will be replacing all of my smoke detectors with these batteries. I have vaulted ceilings and it is a hassle to get to them to change, so a long lasting battery is perfect! Also, I live on the west coast where the temperatures can get very hot, the Energizer Ultimate Lithium is ideal for my needs!! Excellent quality battery.
